回答1:

For me works this:

'multiple'=>true

Your code must be something like that:

<?php echo $form->dropDownList($model,'clients', 
  CHtml::listData(client::model()->findAll(array('order'=>'id')), 'id', 'name'),
     array('empty'=>'','multiple'=>true ,'style'=>'width:400px;','size'=>'10'));
?>

If it is a relation you may want to use this : http://yiiext.github.com/activerecord-relation-behavior/ which takes care of saving array into many to many relation junction table.

Otherwise, like Orlymee said, you need to save each item of the array by looping through it or you can serialize the array or implode it into comma separated values and do the reverse of whatever method you chose to save, while viewing.

回答3:

keep this code in controller

$arr = implode(",",$model->attributes['hobbies']);

$model->hobbies=$arr;

in controler create,update in the first if condition

in database you can see the values with comma as delimiter

$htmlOptions = array('size' => '5', 'multiple' => 'true','style'=>'width: 333px');

$model->field_id    =   array_of_data_to_be_selected

$form->listBox($model,'field_id',$listData, $htmlOptions);

回答5:

How does this work in CHtml::listBox()

if(!empty($htmlOptions['multiple']))
{
    if(substr($name,-2)!=='[]')
        $name.='[]';
}

So you can try this

<?php echo $form->dropDownList($model,'clients', 
    CHtml::listData(client::model()->findAll(array('order'=>'id')), 'id', 'name'),
    array(
>>>     'name'=>CHtml::resolveName($model, 'clients').'[]',
        'empty'=>'',
        'multiple'=>'multiple',
        'style'=>'width:400px;',
        'size'=>'10',
    )
);?>

But it's better to use CHtml::listBox()
